;;; Commentary:
|
|
|
|
;; The Arch version control system website is at
|
|
;;
|
|
;; https://www.gnu.org/software/gnu-arch/
|
|
;;
|
|
;; This is derived from vc-mcvs.el as follows:
|
|
;; - cp vc-mcvs.el vc-arch.el and then M-% mcvs RET arch RET
|
|
;;
|
|
;; Then of course started the hacking.
|
|
;;
|
|
;; What has been partly tested:
|
|
;; - Open a file.
|
|
;; - C-x v = without any prefix arg.
|
|
;; - C-x v v to commit a change to a single file.
|
|
|
|
;; Bugs:
|
|
|
|
;; - *vc-log*'s initial content lacks the `Summary:' lines.
|
|
;; - All files under the tree are considered as "under Arch's control"
|
|
;; without regards to =tagging-method and such.
|
|
;; - Files are always considered as `edited'.
|
|
;; - C-x v l does not work.
|
|
;; - C-x v i does not work.
|
|
;; - C-x v ~ does not work.
|
|
;; - C-x v u does not work.
|
|
;; - C-x v s does not work.
|
|
;; - C-x v r does not work.
|
|
;; - VC directory listings do not work.
|
|
;; - And more...
